Jenny compared the average temperature and annual rainfall for two towns in the same state. The results are shown in the data table. From these results, Jenny concluded that hotter weather causes more rain to fall. What is another reasonable interpretation of this data?



A. Farmon is a very cold place to live.

B. Colder weather causes more rain to fall.

C. Rain causes the temperature to increase.

D. Davis is the rainiest town in the entire state.

Chris wanted to determine the effects of a soil pollutant on the growth of a sunflower plant. He designed an experiment and recorded his results in the data table. Where does Chris make a mistake in the design of his experiment?


A. The experiment doesn’t have a control.

B. The experiment should use more types of plants.

C. The amount of water should be the same for each plant.

D. The amount of pollutant should be the same for each plant.
Correct response: C

GLE 26—Use and describe alternate methods for investigating different types of testable questions

Lamont has two blocks of metal. The blocks are both the same size, as shown below.



Block 1 Block 2

Lamont wants to show that the blocks are made from different metals. One way to do this is to show that Block 2 has a different melting temperature than Block 1. However, this would require a very powerful heat source.


Which of these is another way Lamont could show that the blocks are made from different metals?
A. Show that both blocks conduct electricity.

B. Show that the blocks weigh different amounts.

C. Show that both blocks can be picked up by a magnet.

D. Show that the blocks come from two different regions on Earth.

Correct response: B
